Description:
This is an versatile folding Treeview menu
using YUI's
treeview control. It lets you define a collapsible tree with support
for arbitrary number of levels, plus the ability to make any node a link with
it! YUI may not be the easiest
thing to work with for beginners, which is why we've created a custom function
on top of it to simply the process of creating a tree, adding levels, and making
a node a link etc. All you have to do is call one function. There's no stopping
you now!
